BiologyCellular processesA2/A-levelOCR Created by: Amy CockingCreated on: 04-01-14 13:23 the 3 light dependent reactions photophosphorylation, photolysis, production of reduced NADP 1 of 21 An important enzyme used to combine CO2 with a 5carbon acceptor molecule Rubisco ( Ribulose Bisphosphate Carboxylase) 2 of 21 both reactions occur where? in the chloroplasts 3 of 21 the light dependent reaction occur in the? thylakoid 4 of 21 the light independent reaction occurs in the? stroma 5 of 21 the master pigment is called Chlorophyll A 6 of 21 2 types of chlorophyll A? P680 and P700 7 of 21 Examples of accessory pigments? Xanthophyll and Chlorophyll B 8 of 21 The 2 chlorophylls and their accessory pigments are called? Photosystem 1 and photosystem 2 9 of 21 Products of the light dependent reaction? ATP, reduced NADP 10 of 21 Autotroph organisms that make organic molecules from inorganic molecules 11 of 21 Heterotroph rely on other organisms from whom they feed or digest their organic molecules 12 of 21 what is photolysis the energy from excited chlorophyll A splits water into protons, electrons and oxygen 13 of 21 what is photophosphorylation energy from excited chlorophyll A's electrons is used to create ATP 14 of 21 another name for the light independent reaction? calvin cycle 15 of 21 Process of calvin cycle CO2 + ribulose bisphosphate - gylcerate-3-phosphate - triose phosphate - either glucose or ribulose phosphate 16 of 21 Variables influencing photosynthesis availability of water, light intensity, wavelength of light and temperature 17 of 21 Action Spectra shows how active the pigments included in photosynthesis are at wavelengths 18 of 21 Absorption Spectra shows what light is absorbed and reflected 19 of 21 what is non-cyclic photophosohorylation photosynthesis is usually non-cyclic - electrons pass on one direction from PS2 to PS1 20 of 21 what is cyclic photophosphorylation if a plant needs to make morr ATP, the electrons can pass back to PS2 at the end of the ETC 21 of 21
